Since last year it has risen several hundred dollars and from just two years ago alone it has risen almost one and half thousand dollars. Location will be a factor in how high or low costs will average, even just going outside of city limits the price will be lower. The month, day and time will also be a factor. Weekends being the most active and highly sought after will be more expensive of course as well as popular wedding months.
